Problems solved by technology

As the country's requirements for resources and environmental protection are getting higher and higher, how to maximize the comprehensive recycling and utilization of raw materials for the production of mechanism charcoal has become an inevitable technology development. At present, there is a production technology that uses traditional Chinese medicine residues to produce activated carbon. , but due to the complex technology and difficult control, it is difficult to be practically applied in the industry, and the existing mechanism charcoal preparation process usually needs to add binders, which greatly increases the cost of mechanism charcoal preparation. In addition, the binder The addition of additives will have a certain impact on the health of processors and users

Embodiment 1

[0031] Example 1: Select 20 parts of corncobs, 20 parts of sawdust, 30 parts of rice straw, 5 parts of pine cones, 5 parts of nut shells, 15 parts of medicinal dregs, and 5 parts of adhesives as the main raw materials, and use corncobs, sawdust, rice Straw, pine cones, and chestnut husks are put into the pulverizer for crushing to obtain mixed powder, and the particle size of the mixed powder is 8mm; the raw material of medicinal dregs is first soaked to remove sand and gravel, and then dried in the sun for 1 day and then used The drying equipment is dried at 180°C. When the water content in the raw material is 8%, the raw material is taken out and crushed, and it is the crushed medicinal residue; mix the mixed powder and the crushed medicinal residue together, and after mixing evenly, add The adhesive composed of dextrin, starch and clay is then stirred evenly, and finally sent to the dryer for drying. The drying temperature is 150°C and the drying time is 3 hours; the dried r...

Embodiment 2

[0032] Embodiment 2: Step 1: selection of raw materials, choose 22 parts of corn cobs, 15 parts of sawdust, 30 parts of corn stalks, 3 parts of pine cones, 8 parts of peanut shells, 15 parts of medicinal dregs, and 7 parts of binders as the main raw materials; Put corncobs, sawdust, corn stalks, pine cones, and peanut shells into the pulverizer for crushing to obtain a mixed powder, where the particle size of the mixed powder is 10 mm; Dry in the sun for 2 days and then use drying equipment to dry at 220°C. When the moisture content in the raw material is 10%, take out the raw material and crush it to become the crushed medicinal residue; mix the powder and crushed medicinal residue Mix together, after mixing evenly, add the adhesive composed of dextrin, starch and clay, then stir evenly, and finally send it into the dryer for drying. The drying temperature is 180°C, and the drying time is 3.5h; Send the dried raw materials to the extruder to extrude into various shapes of sha...

Abstract

The invention discloses a preparation method of machine-made wood charcoal, belonging to the technical field of wood charcoal processing. The preparation process comprises the following steps: raw material selection: selecting corn cobs, sawdust, plant straws, pinecones, nutshells, medicine dregs and an adhesive as main raw materials; raw material treatment: mixing the raw materials, and drying the raw materials at 150-200 DEG C for 3-4 hours; sending the raw materials into an extruding machine, and extruding into coal briquettes in various shapes; and putting the coal briquettes into a kiln, firing for about 2-3 days, taking out, and cooling to obtain the high-temperature machine-made wood charcoal. The traditional Chinese medicine dregs are used as the raw material to produce the machine-made wood charcoal, thereby implementing comprehensive recycling on the traditional Chinese medicine dregs, and reducing the pollution of the traditional Chinese medicine dregs on the environment. The adhesive is a natural adhesive, does not generate harmful substances after being combusted, does not pollute the environment or jeopardize human health, and is very environment-friendly. The detection proves that various indexes of the wood charcoal produced by the method satisfy related national standards.

Description

Technical field: [0001] The invention relates to a preparation method of machine-made charcoal, belonging to the technical field of charcoal processing. Background technique: [0002] Mechanism charcoal is also known as mechanism charcoal, salary stick, artificial charcoal, regenerated charcoal, smokeless clean charcoal, and stick charcoal has a wide range of raw materials, such as rice husk, peanut shell, cotton husk, corn cob, corn stalk, sorghum stalk, etc. The raw materials for producing stick charcoal are best sawdust, shavings, and bamboo chips. Because the mechanism charcoal is smokeless, odorless and non-toxic, it has been widely used for home heating and barbecue food; in the industrial field, it can be used as industrial raw materials and further processed into activated carbon, etc. Due to its high density, high calorific value, smokeless, odorless, pollution-free, non-explosive and flammable charcoal, it is an internationally recognized green product. [0003] ...
